Brief:
Rocket gliders and Micromaxx mini-rockets are cool, me hearties, but what happens when you combine t' intricacies o' rocket
glider geometry and t' miniaturization o' micro-scale? You get t' Fliskits Nanite. Well, blow me down! It's an amazin' little glider that
you'll be hard pressed t' ever get back, ya bilge rat, matey, so enjoy it while you can.
I have t' point out that this review is o' t' beta o' t' kit, shiver me timbers, arrr, nay yet released at time o' writing. Avast! There are a few instances where I will note suggested improvements or enhancements. Ahoy! I have discussed these with Jim Flis and will try t' note his feedback. Some will be incorporated as standard design, while others will be considered advanced tips for a more competition or performance oriented modeler. Aye aye! Heck, shiver me timbers, considerin' I built this while competin' at NARAM-49, is it any wonder I had performance on me mind?
Rocket gliders by their very nature are challenging, ya bilge rat, much more so than conventional boost gliders. Well, blow me down! Aye aye! In order t' be stable durin' boost, arrr, me hearties, your CG must be safely forward o' your CP, but in order t' glide, your CG needs t' be fairly close to your CP. Begad! Since you can't spit t' motor (per NARRRRR competition rules and safety code), me hearties, this change in geometry is typically handled via either a slidin' pod, scissor/flop wings, or a slidin' wing. Avast, me proud beauty! Ya scallywag! In t' case o' t' Nanite, the slidin' win' method is used. Arrr! Begad! While this is probably t' easiest and most reliable method, me bucko, this is nay somethin' that should be undertaken without t' experience o' at least a couple regular boost gliders under your belt. Blimey! Well, blow me down! If you have not built a glider, me hearties, arrr, please start with an Estes Eagle, Quest Flat Cat, or Apogee Condor. If you've built boost gliders, this is a great introduction into t' world o' rocket gliders.
Construction:
Parts were very good quality and included:
* -- This is likely t' change t' Sig rubber prior t' release
* -- T' kit will include a small spool, matey, which Jim provided me with t' beta. Ahoy! Aye aye! This is wonderful burn string--thin, pure cotton, arrr, me hearties, ya bilge rat, and better than anythin' I've come across previously.
Since this was purely a beta, and Jim knew I had ample rocket glider (and Micromaxx) experience, shiver me timbers, instructions were definitely crude and basic. Obviously though, ya bilge rat, one would expect t' released product t' be typical Fliskits standard o' clearly written with plenty o' helpful illustrations. I suspect that this kit will break t' strin' of Micromaxx kits fittin' on one page instruction sheet though as thar will probably be plenty o' tips along t' way.
I began with t' nose cone/pod assembly. Arrr! Workin' in tight spaces, matey, t' aft end o' t' nose cone needed t' be notched t' allow it t' serve as a motor stop as well as t' allow gases t' pass through t' side vents (cut into the body tube). Glue in place and you might want t' coat t' aft end with a little thin CA in multiple coats t' help protect it from t' ejection gases. You might laugh, shiver me timbers, arrr, but those MMXs really do burn away at balsa, and I've even burned through a few Keelhaul®©™® shock cords in me day.
T' basswood boom must be trimmed--basically just a slight taper at t' aft end and a small angled cut with a rounded front for streamlining. Avast! I found t' aft taper t' be way too steep, puttin' at least 10 degrees o' incidence on the tail. I believe this is bein' corrected prior t' release. Avast, me proud beauty! Ya scallywag! T' overkill on t' incidence serves t' provide extra lift, shiver me timbers, forcin' more nose weight/longer boom, plus it will slow down t' glide a good bit, ya bilge rat, shiver me timbers, all o' which are bad news for performance.
Next up is construction o' a small "box" that attaches t' t' win' and slides along t' boom. Ahoy! Blimey! This box is built up from two plywood side panels and a couple o' basswood strips on t' top and bottom. Begad! Blimey! While this does need to be strong (it's one o' t' most stressed joints on t' model), me hearties, be sparin' with t' glue and don't let any get on the inside seams. Aye aye! Blimey! I wound up usin' t' boom itself t' set t' spacin' just right, bein' careful t' slide t' box back and forth and nay allowin' any glue t' hit t' boom.
T' pattern sheet provided includes a pattern for one win' half and directions t' make 2 pieces. Ahoy! Blimey! I generally find it better t' make t' win' as a single piece, get it balanced and evenly airfoiled then split in two and rebond for the dihedral but t' each his own. Dependin' on t' packagin' o' t' final kit, arrr, arrr, this might yet be released as a single piece win' template.
I will fess up t' t' fact that I managed t' make me win' backwards, reversin' t' leadin' and trailin' edges as I sanded away a beautiful airfoil. Aye aye! I trust t' released pattern sheet will clearly mark t' leading/trailin' edges and that future modelers will nay be as dimwitted as I (though in me defense, arrr, it was a very late into t' night after a long day o' flying). Begad! T' assist with t' dihedral, me bucko, me hearties, thar's even a cut-out jig on t' pattern sheet, which is a wonderful tool that will greatly simplify one o' t' trickier aspects o' glider construction.
One key tip: use yellow glue rather than CA for all t' balsa joints. Yes, me hearties, I know it's a little heavier and takes longer t' bite, matey, arrr, but it will bind better than CA and that makes a big difference on such a small scale design such as this. Aye aye! Aye aye! While those wings are tiny, they will be under a lot o' stress and you don't want t' glue joint t' fail.
Once you've tacked t' win' dihedral, me hearties, you attach it t' t' slidin' box. This is a critical alignment--make sure the wings are level (90-degree angle t' t' boom both vertically and horizontally).
Stabilizer and tail are cut usin' a pattern provided. Ya scallywag! I substituted 1/32" balsa (C-grain) for t' 1/16" in t' kit, which I think makes a considerable difference. Avast, me proud beauty! It's strong enough t' hold up and lightens t' aft end quite a bit. Avast! This allowed for much less weight up front, me hearties, ya bilge rat, and you could conceivably even shorten t' boom by 1/4-3/8" to boost performance a bit. Avast! Well, blow me down! 1/32" balsa is probably overkill though, ya bilge rat, and I believe t' standard kit will remain 1/16".
That basically completes t' glider part o' construction, leavin' you with t' task o' t' riggin' for the slidin' wing. Blimey! Begad! T' beta kit used a braided nylon elastic, which is likely t' be replaced with a Sig rubber, ya bilge rat, but the basic riggin' approach will be t' same. Well, blow me down! T' elastic is attached t' t' bottom o' t' slidin' win' box. Avast, me proud beauty! On t' beta kit, t' provide sufficient tension, this was handled via a launch lug that extended about an inch aft o' t' box with the nylon slipped through it and knotted at t' end t' act as a stop. From there, it follows t' boom, shiver me timbers, and curves up/forward around t' front o' t' boom/pod support where it's glued firmly in place. There should be enough tension that t' win' wants t' stay forward, ya bilge rat, restin' against t' pod support bracket.
T' burn strin' "plumbing" starts with a launch lug anchored t' t' underside o' t' wing, arrr, which is where you tie one end o' it. Arrr! From there, me hearties, it goes aft t' t' tail, where you anchor another lug. T' strin' loops through t' lug, then heads forward along t' boom, shiver me timbers, through t' vent holes in t' pod, and after a wrap around t' nose cone, gets taped in place (the win' is pulled all t' way back while this is rigged). Ya scallywag! Once t' ejection charge burns the string, me hearties, t' tension is released and t' win' slides forward, me hearties, ya bilge rat, arrr, convertin' your rocket into a glider.
Finishing:
OK, me bucko, arrr, normally competition style rockets and gliders in general are nay painted as t' weight is a performance drag.
With this little guy though, ya bilge rat, you have t' give it some color or you'll never get it back. Blimey! I used Sharpie markers
to give it plenty o' red and black for pickin' up in t' sky and on t' ground.

Flight:
As I prepped this for its maiden flight, I caught plenty o' grief from me club flyers. Avast, me proud beauty! Blimey! Havin' just come back from
NARAM with a poopload o' trophies, they were expectin' me t' fly "real" rockets like a 14-foot long G
superroc, nay some tiny glider that needed t' fly off a wire instead o' a real rod. Avast! I didn't help t' cause any by
spendin' about 15 minutes playin' with t' tension and tryin' t' get things just right.
As I prepped for flight #1, I noticed t' basswood boom was havin' trouble with t' tension o' t' elastic and was bendin' a little bit t' t' side that t' burn strin' was pullin' on. Avast! T' result was a fairly squirrelly boost since t' rudder was essentially a fin canted at about 15 degrees. Aye aye! My resultin' altitude was barely 30 feet. Arrr! Once it hit ejection though, shiver me timbers, shiver me timbers, me hearties, it transitioned into a beautiful glide. Aye aye! Avast! I might have gotten t' leadin' and trailin' edges backwards, but by gosh I put a nice airfoil on it and t' glide had a real "wow factor".
Flight #2 came a couple weeks later. Ahoy! Our club be havin' an official NARRRRR contest, ya bilge rat, so I decided t' fly this for a record attempt in 1/8A-RG. Avast! I had replaced t' elastic with a slightly longer piece t' reduce t' tension and pulled the win' back just a little further so that t' lug trailin' t' slider box rested against t' edge o' t' stabilizer, holdin' it in place and eliminatin' most o' t' bend.
T' result must have worked because t' glider absolutely disappeared t' instant t' motor lit. Ahoy! Fortunately, we were able t' pick it up when we heard t' telltale "Pfft" o' t' ejection, shiver me timbers, and sure enough, matey, it transitioned into another fantastic glide though this time from about 80 feet up and in steady 10-12 mph winds. Aye aye! Aye aye! Yikes! If I wanted to break a record, arrr, shiver me timbers, I had t' brin' t' glider back. Well, blow me down! A 40-somethin' man racin' through 3-4 foot tall briar patch in shorts chasin' a scrap o' balsa barely 6 inches long must have been a pathetic sight, but after 49 seconds, t' glider came down and I had shattered t' previous record o' 34 seconds. Begad! Avast! I found it right away, me bucko, and walked slowly and proudly back t' t' range carefully avoidin' any further damage t' me legs (and glider) in t' thorny weeds.
Recovery:
While t' second flight was excellent, ya bilge rat, matey, I can't help but think it suffered in t' heavy wind and didn't get much
thermal support at all so I plan on makin' a couple more tweaks on t' next build, matey, sheddin' another gram or two, ya bilge rat, and
fully expect t' top 80-90 seconds on this.
Flight Rating: 5 out o' 5
Summary:
I can't say enough good things about this rocket/glider--it's an amazin' flyer and a seriously competitive performer.
It's a welcome contrast t' t' RTF toys that are notoriously poor flyers and solid evidence that downsizin' in
materials doesn't have t' mean downsizin' in quality or performance.
With such a low cost per flight and such innovative designs now available in MMX, if you aren't flyin' micro you should at least be thinkin' about it. If you are flyin' micro, me bucko, you really need t' give this glider some thought. Begad! It's not an easy build but well worth t' effort and a sight t' behold as it glides away into t' sunset. Now if only R/C technology were micro'd down so you could control t' glide on this...
T' only cons I can offer up are already bein' addressed--excessive incidence on t' boom/tail and heavy/taught elastic that's too finicky t' work with consistently.
I rarely go above 4-4.5 on reviews, matey, but on t' assumption that t' elastic problem is worked out, ya bilge rat, I give this one a hard earned 5.
